ABSTRACT:
A motion activated light circuit is comprised of a motion activatable switch which effects switch closures upon displacement thereof for connecting a supply voltage to a pulse generator circuit which generates a predetermined pulse length to provide a control signal at an output thereof. An oscillator circuit is coupled to the control signal of the pulse generator circuit to produce light actuating pulses to feed one of two or more independent light circuits through a light source selection switch. The light source selection switch is conditioned by a sensor which senses ambient light intensity whereby the light actuating pulses are directed to a selected one of the two or more independent light circuits to cause the selected light circuit to generate light pulses.
